Definition
Process Safety Management brings together the controls needed to prevent low-frequency, high-consequence events in hazardous operations. Typical elements include hazard analysis, operating procedures, mechanical integrity, training, incident investigation, emergency planning and management of change. Requirements and terminology vary by jurisdiction.
Why it matters
Process Safety Management matters because hazardous operations can involve low-frequency events with severe consequences. A structured approach helps organizations coordinate hazard analysis, procedures, training, equipment integrity, incident learning and management of change.
Maintain reliable information about hazards, chemistry, equipment, design limits and process conditions so risk decisions have an accurate technical basis.
Process safety information
•
Use methods such as HAZOP, Bowtie Analysis and Risk Assessment to understand major-accident scenarios and the controls relied on.
Hazard identification and risk management
•
Provide clear operating limits, procedures, training and authorization so normal and abnormal operations remain within controlled conditions.
Operational procedures and competence
•
Inspect, test and maintain equipment and Barrier Management arrangements needed to prevent loss of containment or escalation.
Asset integrity and critical barriers
•
Assess technical, organizational and procedural changes before implementation and update dependent documents, competence and safeguards.
Management of Change
•
Prepare for major events and use incidents, audits and performance indicators to strengthen the process-safety system over time.
Emergency response and learning
•
Framework explained
Core elements of Process Safety Management
Process Safety Management coordinates the technical, operational and organizational controls needed to prevent major accidents involving hazardous processes. Effective systems connect process knowledge, risk assessment, operating discipline, asset integrity, change and learning rather than managing each in isolation.
A structured process for evaluating and controlling safety, operational and compliance risks before significant technical, organizational or process changes are implemented.
Management of Change
Process
· Change/HSE
A structured assessment used to identify hazards or uncertainties, estimate their risk and determine whether controls or further action are required.
Risk Assessment
Process
· Risk
European legislation aimed at preventing major accidents involving dangerous substances and limiting their consequences for people and the environment.
